Suggest removal of the ! if user is attempting to call a function as a macro

[TomAFrench]

Consider the program below

fn main() {
    println!(foo);
}

Here we're trying to do a "rusty" println with a ! however in Noir a println is a regular function rather than a macro call.

Compiling this program results in the output

$ nargo compile
error: Expected macro call to return a `Quoted` but found a(n) `()`
  ┌─ src/main.nr:2:5
  │
2 │     println!("foo");
  │     --------------- Macro calls must return quoted values, otherwise there is no code to insert
  │

error: This macro call is to a non-comptime function
  ┌─ src/main.nr:2:5
  │
2 │     println!("foo");
  │     --------------- Macro calls must be to comptime functions
  │

Aborting due to 2 previous errors

These error messages could be improved as we've clearly found the std::println function but we could directly tell the user that they want to remove the ! from the function call in order to call it. For bonus points we can have a code suggestion in the lsp to remove the ! from this call.
